I must be missing something basic. Maybe there’s a Freeper medical professional who can answer this:
Couldn’t the lethal injection be done with an opiate? If so, wouldn’t it be painless? It seems to me (as a layman) that an intentional overdose of heroin or morphine would work.
“Painless” isn’t the opposite of Cruel and Unusual.
Funny how that word seems to take precedent nowadays. Convicted Murderers are not guaranteed a “painless” death, although you would never know it by the discussions of this subject.
Beyond a Reasonable Doubt, the standard for Conviction in our Court System, is not “No Doubt”. At least it wasn’t until all those fantasy CSI Dramas showed up on TV.
